In aqueous solution these two very soluble compounds react to produce a precipitate of lead chloride and a solution of potassium nitrate. Pb(NO3)2 (aq) + 2 KC l(aq) ——-> PbCl2 (s) + 2 KNO3 (aq) Lead chloride precipitates as a solid because of its much lower solubility compared to either lead nitrate, potassium chloride or potassium nitrate.... Decant off the clear limewater solution from above the undissolved solids. Top up the container with water and repeat the process. Magnesium sulfate solution (approximately 0.25 M): Dissolve 15.4 g of hydrated magnesium sulfate (MgSO4.7H2O) in enough water to make 250 cm3 of solution.
